Answer:1
1. 
2. ∠ABC = 120°, ∠BCD = 90°, ∠CDA = 60°, ∠DAB = 90°
Step-by-step explanation:
It's important to note here that the measure of all interior angles in a quadrilateral will add up to 360°
We know this using the formula
, a 4 sided figures angles will add up to
This means that all of the angles (4x, 3x, 2x, 3x) will add up to 360.
Combine like terms:
Divide both sides by 12:
We know now substitute x for 30 in for all of the side lengths.
∠ABC = 4x = 
°
∠BCD = 3x = 
°
∠CDA = 2x = 
°
∠DAB = 3x = °
Hope this helped!
Answer:
The battery was 19 percent when the charging began.
It took 32.4 minutes for the battery to be fully charged.
Step-by-step explanation:
Ok so here we go!
a steam and leaf plot is very simple to figure out
for example if a number was 6|4 it would equal 64
so for your first question range equals the biggest number subtracted by the smallest number so in your case it would be 28-55
which equals 27
Answer:
0.125
Step-by-step explanation:
Answer:
shaded area = total area - the two triangles areas
total area = 5*9 = 45 cm²
first tri area = 1/2 * h *b
= 0.5 * 5 * 2 = 5 cm²
second tri area = 0.5 * 6 * 5 = 15 cm²
shaded area = 45 - 15 - 5 = 25 cm²
